Skippers

Thymelicus sylvestris

Small skipper

Its eggs sit hidden inside a grass stem for months, laid in a neat row before the caterpillar even hatches.

WhereRough grassland, verges, and glades
Size25 to 30 mm wingspan
WhenJune to August

It is a compact orange-brown butterfly that perches with its wings held in a distinctive half-open, moth-like posture, and males show a thin dark line of scent scales across the forewing.

Caterpillars feed inside grass stems and blades, chiefly on Yorkshire fog, and the species produces a single generation each year.
